Definitions

  • the present invention relates to modular refractory fiber blanket furnace lining systems.
  • Refractory fiber blankets made from refractory materials such as chromia-alumina-silica, alumina-silica compositions and zirconia compositions have become desirable as furnace insulation because of their ability to withstand high temperatures.
  • the fiber blanket material has been attached in a layered construction arrangment to the furnace wall using attachment structure, as exemplified in U.S. Pat. Nos. 3,523,395 and 3,605,370.
  • the present invention is an improvement in refactory fiber blanket lining for a furnace wall and the like to prevent erosion of the fibers in the blanket by furnace gases.
  • a surface layer of cloth formed from fibers of metal oxides is mounted on an inner surface portion, termed the "hot face" in the art, exposed to interior conditions in the furnace.
  • the cloth of the surface layer is preferably formed from cloth of woven continuous fibers of alumina-boria-silica composition and is attached to the "hot face" by being sewn thereto with similar fibers.
  • the refractory fiber blanket lining may be in the form of modular insulating blocks of folded blanket or in the form of a plurality of layers, mounted in a substantially parallel relationship with the wall of the furnace.
  • FIGS. 1 and 2 are isometric views of a modular refractory fiber blanket insulating blocks according to the present invention.
  • FIG. 3 is an isometric view of layered refractory fiber blanket furnace insulation according to the present invention.
  • the letter B designates generally an insulating block for lining a wall (not shown), which may be either a side wall or a roof, of a furnace or of some other high temperature equipment such as soaking pits, annealing furnaces, stress relieving units and the like, such as those previously set forth.
  • the insulating block B is preformed from folded insulating blankets, such as a blanket L, for insulating the furnace, with a support S, one of which is shown in phantom, mounted in certain of the folds in the folded blanket and an attachment mounting or channel M for mounting the supports S and the blanket B to the wall.
  • such blanket is formed from a suitable commercially available needled ceramic fiber sheet, such as the type known as "CERABLANKET,” sold by the Johns-Manville Company, containing alumina-silica fibers or other suitable commercially available refractory fibrous materials. It should be understood that the particular component materials of the ceramic fiber sheet used in the blankets are selected based upon the range of temperatures in the high temperature equipment in which the apparatus is to be installed.
  • the blanket L is folded into adjacent layers 10 mounted sinuously and extending inwardly and outwardly in such a sinuous manner between a first end layer 12 and a second end layer 14 at opposite ends of the attachment mounting or channel M.
  • Adjacent ones of the layers 10 and those layers 10 adjacent the end layers 12 and 14 form inner folds 16 adjacent inner end portions 18 of the blanket L near an insulation surface 20, or "hot face" as termed in the art, closest to interior conditions in the high temperature equipment.
  • Outer folds 22 are formed between adjacent layers 10 at an opposite and adjacent outer end portion 24 at positions intermediate each of the inner folds 16.
  • the blanket L is supported at certain of the outer folds 22, designated 22a and 22b (FIG. 1) by a support beam 26, details of which are set forth in an alternate blanket embodiment (FIG. 2) of the support S mounted in the folds 22.
  • the support beam 26 is formed from a folded bar of a high temperature-resistant metal or alloy or other suitable material, although other shapes of support beams and materials may be used, as set forth in Applicant's copending parent application referenced above, now U.S. Pat. No. 3,952,470.
  • the support beam 26 is mounted at a center portion 26a (FIG. 2) thereof within a loop 28 formed at a lower end juncture of suspension arms 30 and 32 of a suspending tab or support tab T of the attachment mounting M.
  • the support beam 26 may be welded, such as by spot welding, and the loop 28 and the suspension arms 30 and 32 welded together for additional strength and support, if desired.
  • the suspending tab T may be formed with a single suspension arm.
  • An opening is formed in the center portion 26a of the U-shaped support beam 26, and the single suspension arm inserted to extend through such opening.
  • the portion of the suspension arm extending through the opening is then bent to fit against one side of the support beam and secured to the support beam 26 by spot welding the suspension arm thereto.
  • the fibers of material normally extend longitudinally within the layer. Additionally, however, it should be understood that the fibers of the adjacent layers may be needled together in the manner set forth in detail in allowed co-pending parent appliction Ser. No. 603,391, now U.S. Pat. No. 4,001,996 if desired.
  • the direction of the orientation of certain of the fibers in the blanket L is changed from the normal longitudinal extension to a position where in adjacent layers are transversely disposed to the remainder of the fibers and extend into other adjacent layers to bind the layers together into an insulating block. In this manner, the perpendicular fibers bind the adjacent lamina or layers of the blanket together, compacting and strengthening the blanket.
  • An opening is formed through the outer end portions 24 of the blanket L adjacent the fold 22 receiving the support beam 26 (FIG. 2).
  • the opening so formed extends upwardly through the blanket L from the fold 22 for passage of the suspension arms 30 and 32 through the blanket L.
  • Mounting lugs 30a and 32a (FIG. 1), formed at upper ends of the suspension arms 30 and 32, respectively, of each of the support tabs or suspending tabs T extend upwardly through mounting orifices 38 in a central attachment channel or a stringer channel member 40 of the attachment mounting M.
  • the mounting lugs 30a and 32a are folded downwardly against the stringer channel member so that the block B may be mounted against the wall.
  • the ends of mounting lugs 30a and 32a may in addition, if desired, be inserted to extend downwardly through mounting orifices 39 in the attachment mounting M so that sharp ends of the tabs T are enclosed beneath the attachment mounting M.
  • the insertion of the ends of the lugs 30a and 32a through the mounting orifices 39 protects the hands of installers against points or sharp surfaces at the ends and, in addition, further strengthens the connection of the supports to the attachment mounting M.
  • each of the attachment mountings M has an attachment receptacle R formed at an end thereof and an attachment pin member P formed at an end opposite the attachment receptacle R.
  • the attachment receptacle R of the apparatus receives the attachment pin P of an adjacent block of the apparatus, while the attachment pin P extends outwardly beyond the preformed insulation block B to provide access for welding in order to mount the block to the furnace wall. After such mounting, the pin P is fitted into an attachment receptacle R of another adjacent block B.
  • furnace gases often achieve sufficiently high velocity to carry away individual fibers in the blanket L due to the high velocity gas movement.
  • the problem is further compounded in target areas where burners impinge, causing the fibers to be susceptible to possible devitrification, making the fibers more erosible.
  • a surface layer C of cloth formed from fibers of metal oxides is attached to the hot face 20 of the block B exposed to interior conditions of the furnace.
  • the cloth of the surface layer C is preferably formed by being woven from metal oxide thread, preferably a continuous filament metal oxide thread which, when woven, yields a ceramic cloth.
  • a suitable cloth for example, is that woven from the ceramic fibers designated AB-312 of the 3M Company of Saint Paul, Minn. These fibers are continuous filaments of alumina-boria-silica composition and are commercially available from the 3M Company. Further details of the fibers and their composition and characteristics are set forth in Design News magazine in the May 10, 1976 issue. These fibers are there stated to withstand continuous usage temperatures of 2600° F.
  • the cloth of the surface layer C once woven, is attached to the hot face 20 by any suitable technique, such as, for example, by being sewn thereto with fibers of the type from which the cloth is woven.
  • the surface layer of cloth effectively retains the underlying fibers of the blanket L with the block B so that the high velocity furnace gases do not carry the fibers away and erode the block B.
  • any fibers which might devitrify are in a like manner protected from the high velocity furnace gases and possible eroding action of such gases.
  • the block B when formed in the manner set forth above, is then attached to the wall of the furnace or high-temperature equipment in the manner set forth in Applicant's parent application previously referenced, now U.S. Pat. No. 3,952,470.
  • the invention may take the form of several other embodiments.
  • like structure performing like functions bears like reference numerals.
  • second embodiment B-1 (FIG. 2) of a modular insulating block, a refractory fiber blanket L-1, formed from a single piece of suitable ceramic fiber insulating material, is first folded to form an inner surface portion 120c which is exposed along an interior insulation surface 120, or "hot face,” to interior conditions in the high temperature equipment.
  • Side surface portions 120a and 120b of the blanket L-1 extend outwardly from each end of the inner surface portion 120c toward the wall of the furnace to a fold 22 formed therein for receiving a support S in the manner previously set forth.
  • Inner wall member portions 122 adjacent the side surface portions 120a and 120b, respectively, extend inwardly from the fold 22 to an interior surface 124 of the inner surface portion 120c opposite the insulation surface 120 thereof.
  • the inner wall member portions 122 and the side surface portions 120a and 120b, respectively, may, if desired, be needled together in the manner set forth above.
  • the block B-1 has suitable attachment structure, in a like manner to the block B, by which it may be mounted to the furnace wall in a like manner to either the block B, or in the manner disclosed in co-pending U.S. patent application No. 603,391, now U.S. Pat. No. 4,001,996 identified above.
  • This bulk material may be contained temporarily in a plastic or fiber container which burns and is consumed when the insulating block is exposed to the heat of the furnace.
  • fiber insulating board or mats may be used in place of the mass 130 of bulk ceramic fibers, as set forth in U.S. patent application Ser. No. 603,391, now U.S. Pat. No. 4,001,996 previously referenced.
  • the block B-1 in a like manner to the block B has a surface layer of cloth C of the type set forth above attached thereto in the manner set forth above.
  • the surface layer of cloth C retains the underlying short staple of fibers therewithin and prevents erosion of such fibers.
  • the present invention is further adapted for use with layered refractory fiber blanket furnace insulation.
  • a plurality of layers 140 of refractory fiber blanket are shown mounted in a substantially parallel relationship with a wall 142 of the furnace.
  • the layers 140 may, for example, be attached with the wall 142 in the manner set forth in U.S. Pat. No. 3,523,395, or by other suitable techniques.
  • a surface layer of cloth C is attached thereto in the manner set forth above.
  • the cloth C retains the fibers of the layers 140 therein, protecting them from the erosive effects of the high velocity furnace gases.
  • the apparatus of the present invention is also suitable to insulate or form cryogenic, or low temperature equipment, as well.
